Patent GB-149329-A (GB)
IPC: B63H23/00
Abstract: 149,329. Westinghouse Gear & Dynamometer Co., (Assignees of Macalpine, J. H.). July 17, 1919, [Convention date]. Toothed gearing.-A floating frame for large double helical and like toothed reducing-gearing is stiffened by a periphery of hollow or box-like formation, the upper part accommodating a lubricant conduit from which passages lead to the bearings and gear elements. The arrangement shown comprises a marine installation for transmitting power at a reduced speed from a turbine to a propeller shaft, in which a high-speed shaft 6, Fig. 2, mounted in a suitable floating frame '7 meshes with gears 8 on an intermediate floating shaft 9 which carries pinions 10 transmitting the drive to a large or final gear 11 mounted in rigid bearings. The intermediate shaft 9 is mounted in the floating frame 5 which is free to move angularly about an horizontal axis approximately normal to the shaft, being supported centrally at 26 on I-beams 13a carried by pedestals 13 in the casing 12, movement about a vertical axis being prevented by struts 14. The frame 5, Figs. 1, 4, and 5, is formed in halves bolted together and comprises a peripheral portion 15 of box-like form as shown with a central web 21 lightened by holes and with transverse ribs or flanges 23. The box-like portions are strengthened by numerous internal ribs or flanges 25, and are formed with holes 27<a> serving as core supports in making the castings, these being closed if desired by pipe plugs. A central box-like strut 18 is formed with a suitable base 26 adapted to rest on the I-beams 13<a>, and is also formed with a central bearing 19 for the shaft 9, the ends of which are supported in bearings 16, 17. The pinions 10 are partly enclosed by casings 22, Fig. 5, supported by the webs 21 and communicating with lubricating passages or chambers 38 arranged at the back thereof. An oil or lubricant conduit 27b extends through the upper portion of the frame 5, having inlet ports 28, 29, 30, and, through vertical passages 31, 32, 33, supplies annular oil chambers 35 round the bearings 16, 17, 19, passages 37 leading from the annular chambers to the bearings. The annular chambers of the end bearings 16, 17 communicate directly with the passages or chambers 38 which supply lubricant to the casings 22 through holes 39, ribs 44 being provided to maintain even distribution over the gear surfaces. Restricted openings are formed in partitions in the chambers 38, through which the oil must flow before it reaches the outlets 39. This enables lubricant to be supplied to the bearings under pressure. From the chambers 38 restricted passages 43 lead to pockets 40 over the casings 22, from which lubricant flows through passages 41 to the intermeshing gear surfaces. Channels 45 are formed in the outer walls of the pockets to distribute the oil in the case of an overflow. In a modification, the upper portion of the box-like periphery of the frame 5 is formed as a lubricant conduit and reservoir.

Patent GB-1313114-A (GB)
Title: Method and apparatus for producing trigger pulses
IPC: F02P7/077
Filed: 1970-03-31
Abstract: 1313114 Digital measurements G HARTIG 31 March 1970 [3 April 1969 9 March 1970] 15063/70 Heading G4H [Also in Division F1] In a method of generating a timing pulse for a mechanism with periodic motion relative to a fixed point in that motion, such as for an ignition pulse for an internal combustion engine (ICE) relative to top dead centre, for each period of the motion pulses are generated by the motion which are counted for a predetermined period, which is variable according to, say engine temperature, and then at a predetermined point in the periodic motion the pulses are further counted during a second period until the count reaches a predetermined count whereupon the timing pulse is generated. In the arrangement of Fig. 2 pulse shaper 11 receives repeatedly a series of pulses generated by the movement of the ICE, there being a gap between adjacent series which circuit 12 detects and issues a zeroising pulse to counter 28 and sets gating circuit 17. From the beginning of the next sequence counter 28 counts pulses and either counter 16 or 21, which alternate in counting for successive sequences, count pulses during a period S defined by gating circuits 17, fed by the predetermined period signal S. Circuit 18 extends period S to a whole number of pulses which are gated via gate 19 to counter 16 or alternatively counter 21. Adder 25 or alternatively adder 27 adds the counts accumulating in counter 28 to the count accumulated during period S of the previous sequence in counter 16 or alternatively counter 21. At a predetermined sum the respective adder generates an ignition pulse at output S. The counters 16 and 21 are switched and zeroed by bi-stable 14 in response to the cancel pulse from circuit 12. Circuit 23 alters the criterion for detecting interseries spacing from circuit 12 if counter 16 or counter 21 receives only one pulse during period S, e.g. in slow running of the engine. In another example (Fig. 5) an impulse wheel 50 coupled to the crank-shaft of an ICE generates pulses according to the speed of the engine. A start pulse generated by sensor 55 and tooth 51a zeroes a counter 59 which starts via OR gate 60 a relaxation oscillator 61 whose pulse defines the predetermined period and opens AND gate 57 to permit counting of pulses from sensor 54. The period ends before both sensors 54 and 55 simultaneously sense teeth. When the sensors sense teeth together the counter further counts pulses from AND gate 64 until a predetermined count is reached, at which the timing pulse is outputted on line 65. In another arrangement (Fig. 8, not shown) the sensors are staggered along the line of scanning and a tooth and a gap of extra width indicate start of the predetermined period and the further period of counting respectively.
